Each honeycomb cell was now perhaps a centimeter and a half across, no bigger than a keycap, as if the whole thing was a vast keyboard.

The closed ends of the honeycomb cells are also an example of geometric efficiency, albeit three-dimensional and little-noticed.

The honeycomb cells were smaller here, and she realized they spiraled down, growing larger as they went, as in many natural shell formations.

It is then stored in honeycomb cells.

Honey sealed in honeycomb cells by the bees is considered by many to be the ideal form for preservation.

Number of eggs per cell The beekeeper looks at the honeycomb cells to see how many eggs are laid in each one.

Inside, in honeycomb cells, nested a dozen slim tubes with egg-bulges at one end and fins at the other.

Raw honey is then spread out in empty honeycomb cells to dry, which reduces the water content to less than 20%.

Honey bees use the beeswax to build honeycomb cells in which their young are raised with honey and pollen cells being capped for storage.

When beekeepers extract the honey, they cut off the wax caps from each honeycomb cell with an uncapping knife or machine.
